Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, a high-diffusion wide-angle LED lamp includes a ceramic substrate 2, electrodes 3 arranged at both ends of the ceramic substrate, an LED chip 1 connected to the electrodes, and a lens 8 covering the LED chip. The lens 8 and the ceramic The base material 2 is fixedly connected and integrated to ensure the accuracy of the axis line and height.

[0019] Further, the lens 8 is connected to the ceramic substrate 2 in the form of silicone molding;

[0020] Further, the upper surface of the lens 8 is a hemispherical curved surface with a flat top;

[0021] An inner concave portion is provided on the upper surface of the lens, the side surface 7 of the inner concave portion is a conical curved surface, and the bottom surface of the inner concave portion is a plane 6;

[0022] The electrodes 3 are arranged on both sides of the ceramic substr...

Abstract

The invention relates to a high-diffusion wide-angle LED lamp which comprises a ceramic substrate, electrodes arranged at the two ends of the ceramic substrate, an LED chip connected with the electrodes and a lens covering the LED chip. The lens is made of silicon in a compression molding mode and is fixedly connected with the ceramic substrate to form a whole. The upper surface of the lens is a semispherical curved face with a plane as the top. A concave portion is arranged in the upper surface of the lens and a side of the concave portion is a cone-shaped curved face. The bottom of the concave portion is a plane. According to the LED lamp, the lens and the substrate are formed at a time, an assembling axis and assembly height are accurate and the high-diffusion wide-angle LED lamp is formed to meet demands of all industries.

Description

technical field [0001] The invention relates to a high-diffusion and wide-angle LED lamp, which belongs to the field of LED lighting. Background technique [0002] LED lights have long been widely used for their environmental protection and high efficiency, and their lighting or backlight needs a wider angle. In order to achieve the required angle of illumination or backlight, at present, most of them use secondary optical lens for light distribution, that is, the lens is placed on the manufactured LED to change the angle of light; this assembly method is easy to produce assembly axis Problems such as deviation and inaccurate assembly height cause halos and affect lighting and backlight effects. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the object of the present invention is to provide an LED lamp with a high diffusion and a wide angle, in which the lens is once formed on the base material. [0004] To achieve the above object, t...
